Simulink Real-Time C API with python, TCP/IP ERROR

I call Simulink Real-Time(speedGoat) C API with python

The error message:

MathWorks.xPCTarget.FrameWork.xPCException:TCP/IP Write ERRIR

在 MathWorks.xPCInvokePI.xPCErroe.handlError(xPCTargetPC tgpc)

在 MathWorks.xPCTarget.FrameWork.xPCSignals.get_NumSignals()

.......
sys.path.append(xpcDLLFolderPath)
clr.AddReference('xPCFrameWork')
import MathWorks.xPCTarget.FrameWork as xpc
tgpc = xpc.xPCTargetPC()
tgpc.DLMFileName = 'xxxx'  # xxxx respent a path
tgpc.TcpIpTargetAddress = '192.168.7.2'
tgpc.TcpIpTargetPort = '22222'
tgpc.Connect()

tgSignals = tgpc.Application.Signals
for i in range(tgSignals.NumSignals):
    tgSignal = tgSignals.get_Item(i)

Hi,

The error you are encountering indicates an issue with writing data over TCP/IP. This could be due to several factors such as incorrect IP address or port or incorrect setup of the Simulink Real-Time environment. 

Go through the following steps to debug your error -

• Please make sure that the “xpcDLLFolderPath” is correctly set to the folder containing the necessary DLLs for the xPCFramework.
• Additionally, double check the values for “TcpIPtargetAddress” and “TcpIpTargetPort” to make sure they match the configuration on your Speedgoat target machine.
• Finally make sure the target computer settings are set properly to match the capabilities of target computer.

You can refer to the following documentation to understand how to configure the target settings - https://www.mathworks.com/help/releases/R2020b/slrealtime/gs/target-computer-settings.html

Thank you for your reply. I found that speedgoat could not be operated through the API when it was connected. Just disconnect speedgoat，it will be ok
